Embodiments of the present disclosure will be described below in detail with reference to the accompanying drawings.

Figure 1A illustrates an isometric view of a first embodiment of a food processor, for performing the wet grinding operation, in accordance with an embodiment of the present disclosure. The food processor 100 may include a first grinding assembly 102 adapted to perform the wet grinding operation removably mounted to a drive assembly 104. The drive assembly 104 may include an electric motor (shown in Figure 3B) to supply rotary power to the first grinding assembly 102. The first grinding assembly 102, described in detail in the description of Figures 1B-1D, is removably mounted to the drive assembly 104 to generate food paste from a plurality of food items.

Figure 1B illustrates a sectional view of the first grinding assembly 102 of the food processor 100 shown in Figure 1A. Figures 1C-1D illustrate exploded views of the first grinding assembly 102 of the food processor 100 shown in Figure 1A.

As used herein, the term “wet grinding operation” may refer to a process of generating a food paste derived from food materials such as grains or lentils in combination with a fluid such as water. The wet grinding operation is more commonly used in Indian cuisine to make pastes from grains and lentils. For example, such pastes are used extensively in South Indian cuisine for the preparation of popular dishes such as dosa, idly, vada, and appam. Wet grinders have two advantages over electric mixers or blenders. First, the stone grinder generates less heat than a mixer; heat affects the flavor of the food. Second, the stones remain sharp for a greater time than do metal blades.

The first grinding assembly 102, disclosed herein may include a base unit 106, a grinding unit 108, and a wet cover unit 118. The base unit 106 may include a gear assembly 120. The base unit 106 may be adapted to be removably coupled to the drive assembly 104 (shown in Figure 3B) to transmit power generated by the drive assembly 104 to a grinding stone 112 of the grinding unit 108. In an embodiment, the gear assembly 120 may include a planetary gear, a sun gear, and a ring gear intermeshed with each other to regulate the transmitted power from the drive assembly 104.

The grinding unit 108 may include the grinding stone 112, a roller stone 110, a container 116, and a wet bowl flow cover 114. The grinding stone 112 may be coupled to the gear assembly 120 to receive rotary power from the gear assembly 120. In an embodiment, the grinding stone 112 may be mounted onto an output shaft of the gear assembly 120. The roller stone 110 may be stationarily mounted vertically above the grinding stone 112 such that the roller stone 110 and the grinding stone 112 are adapted to be housed within the container 116. In an embodiment, the roller stone 110 may be mounted such that a central axis of the roller stone 110 is oriented perpendicular to a central axis of the grinding stone 112.

Further, the container 116 may be adapted to receive at least one of food items and a fluid. In an embodiment, the food items may include grains, lentils, etc. as non-limiting examples, and the fluid may include water. The container 116 includes the wet bowl flow cover 114 to prevent the outflow of at least one of the food items, the fluid, and a ground paste. The rotary motion of the grinding stone 112 relative to the stationary roller stone 110 grinds the received food items and the fluid to the ground paste.

The wet cover unit 118 may be adapted to enclose the grinding unit 108 and adapted to be removably coupled to the base unit 106. Further, an adjusting mechanism may be provided in the wet cover unit 118 to increase or decrease the distance between the grinding stone 112 and the roller stone 110. The adjusting mechanism may include at least one knob 118a, at least one aperture 118b, at least one lid 118c. The at least one aperture 118b may be adapted to receive at least one of the food items and the fluid. The at least one lid 118c may be adapted to securely seal the aperture 118b when the first grinding assembly 102 is not in use.

In an embodiment, the first grinding assembly 102 for performing the wet grinding operation uses water as a lubricant and mixing medium. The knob 118a may be rotated to adjust a distance between the grinding stone 112 and the roller stone 110. The shorter the distance between the grinding stone 112 and the roller stone 110, the finer will be the texture of the generated ground paste. If the knob 118a is adjusted such that the distance between the grinding stone 112 and the roller stone 110 is increased, then the ground paste will have a coarse texture due to the presence of larger-sized food ingredients. In an embodiment, the knob 118a may be rotated in one of a clockwise direction and an anti-clockwise direction to vertically move the roller stone 110. By adjusting the distance between the grinding stone 112 and the roller stone 110, the required particle size of the ground food ingredients may be achieved. A user may add water and food ingredients during operation by removing the lid 118c provided on top of the first grinding assembly 102 as necessary. The output of the first grinding assembly 102 will be food ingredients as a paste or batter.

As used herein, the term “dry grinding operation” may refer to a process of generating food powder from spices or leaves, such as pepper, turmeric, etc. The dry grinding operation serves to generate a dry food powder with minimal moisture content. The presence of moisture influences powder increases the cohesiveness of the powder particles. Moreover, the presence of moisture reduces the shelf life of the processed food powder. Therefore, the moisture content must be suitably low to generate food powder having optimum characteristics such as low cohesiveness between powder particles and increased shelf life.

Figure 2A illustrates an isometric view of a second embodiment of a food processor 200 for performing the dry grinding operation, in accordance with an embodiment of the present disclosure. The food processor 200 may include a second grinding assembly 202 adapted to perform the dry grinding operation removably mounted to the drive assembly 104. The drive assembly 104 may include an electric motor (shown in Figure 3B) to supply rotary power to the second grinding assembly 202. The second grinding assembly 202, described in detail in the description of Figures 2B-2D, is removably mounted to the drive assembly 104 to generate the dry food powder from the plurality of food items.

Figure 2B illustrates a sectional view of the second grinding assembly 202 of the food processor 200 shown in Figure 2A. Figures 2C-2D illustrate exploded views of the second grinding assembly 202 of the food processor 200 shown in Figure 2A in accordance with an embodiment of the present disclosure. For the sake of brevity, Figures 2B-2D are described together. The second grinding assembly 202, disclosed herein, may include a base unit 208, a grinding unit 216, and a cover 206. The base unit 208 is adapted to be removably coupled to the drive assembly 104 to transmit power generated by the drive assembly 104 to a rotary grinding stone 216c of the grinding unit 216.

Further, the grinding unit 216 may include the rotary grinding stone 216c and a stationary grinding stone 216a. The rotary grinding stone 216c is coupled to is attached to the base unit 208 and the base unit 208 is coupled to the drive assembly 104 to receive rotary power from the drive assembly 104. Furthermore, the stationary grinding stone 216a may be firmly mounted vertically above the rotary grinding stone 216c. In an embodiment, the stationary grinding stone 216a and the rotary grinding stone 216c are adapted to be housed within the cover 206 and biased relative to each other by spring elements 216b. Moreover, the rotary motion of the rotary grinding stone 216c relative to the stationary grinding stone 216a facilitates in grinding the received food items to ground powder.

The cover 206 may be adapted to be removably coupled to the base unit 208 and to prevent outflow of at least one of the food items and the ground powder. In an embodiment, the cover 206 may be snap fit onto the base unit 208. The cover 206 may include a hopper 204 and at least one aperture 212 defined in the cover 206. The hopper 204 may be adapted to receive food items and may be securely sealed during operation using a hopper lid 210. Further, an adjusting mechanism may be provided in the cover 206 to increase or decrease the distance between the distance between the stationary grinding stone 216a and the rotary grinding stone 216c. The aperture 212 may be defined on a side portion of the cover 206 for receiving at least one locker knob 214.

The locker knob 214 may be adapted to actuate the stationary grinding stone 216a towards the rotary grinding stone 216c or away from the rotary grinding stone 216c. The user may adjust the locker knob 214 to reduce or increase the distance between the stationary grinding stone 216a and the rotary grinding stone 216c. The shorter the distance between the stationary grinding stone 216a and the rotary grinding stone 216c, the finer will be the texture of the generated ground powder. If the locker knob 214 is adjusted such that the distance between the stationary grinding stone 216a and the rotary grinding stone 216c is increased, the ground powder may have a coarse texture due to the presence of larger sized food ingredients. By adjusting the distance between the stationary grinding stone 216a and the rotary grinding stone 216c, the desired particle size is achieved.

Further, the second grinding assembly 202, disclosed herein, is adapted to receive the food items through the hopper 204 after opening the hopper lid 210. The distance between the stationary grinding stone 216a and the rotary grinding stone 216c is adjusted by moving the locker knob 214 to the desired position in the aperture 212. The selected distance between the stationary grinding stone 216a and the rotary grinding stone 216c determines the size of the food ingredients in the ground powder. In an embodiment, the movement of the stationary grinding stone 216a and the rotary grinding stone 216c is maintained by the spring elements 216b. The output of the second grinding assembly 202 will be food ingredients in powder form.

In certain implementations according to the disclosure, the stationary grinding stone 216a and the rotary grinding stone 216c may be replaced by oil extraction stones, and the output will be oil. In such an embodiment, at least one spout area or a dispensing aperture may be provided to extract the ground oil from the oil extraction stones. Further, a filter may be provided near the spout area or the dispensing aperture for separating ground sludge from extracted oil.

Figure 3A illustrates a perspective view of the drive assembly 104 of the food processor 100, 200 shown in Figures 1A and 2A, according to an embodiment of the present disclosure. Figure 3B illustrates an exploded view of the drive assembly 104 shown in Figure 3A, according to an embodiment of the present disclosure. To perform the wet grinding operation, the first grinding assembly 102 of the food processor 100 may be mounted to the drive assembly 104 as shown and described in the detailed description of Figures 1A-1D. Alternatively, to perform the wet grinding operation, the second grinding assembly 202 of the food processor 200 may be mounted to the drive assembly 104 as shown and described in the detailed description of Figures 2A-2D.

In an embodiment, the drive assembly 104 includes an electric motor 306 to supply rotary power one of the first grinding assembly 102 and the second grinding assembly 202. In an embodiment, both the grinding assemblies 102 and 202 units are powered by the electric motor 306 such as a 400 W high-powered induction motor assembly along with a 10 micro-Farad Capacitor for starting. In the food processor 200, the second grinding assembly 202 is adapted to receive power from the drive assembly 104 and rotate the rotary grinding stone 216c in a second predetermined speed. In an embodiment, the second predetermined speed is in a range from 140 Rotations Per Minute (RPM) to 140 RPM. Similarly, in the food processor 100, the base unit 106 is adapted to receive power from the drive assembly 104 and rotate the grinding unit 108 in a first predetermined speed. In an embodiment, the first predetermined speed is in a range from 1400 RPM to 1500 RPM. The speed of the first grinding assembly 102 is controlled by the gear assembly 120. In an embodiment, the gear assembly 120 is manufactured using a powder metallurgy process. The powder metallurgy process is a material addition process in which powdered metal is subjected to high temperature and pressure to get a compact solid part. The powder metallurgy process is already known in the art, therefore not described in detail to maintain the brevity of the specification.

In an embodiment, the electric motor 306 may be housed in a motor duct housing 308 and enclosed by a base unit 310 connected to a main body cover unit 302. The main body cover unit 302 includes a top portion having an interconnecting element adapted to securely engage the first grinding assembly 102 and the second grinding assembly 202. Further, the main body cover unit 302 includes handle portions 304 for the user to hold and move the drive assembly 104 easily. In an embodiment, the drive assembly 104 also includes a plurality of rubber feet 312 connected to the base unit 310 to prevent slippage of the drive assembly 104 during operation.

Both the first grinding assembly 102 and the second grinding assembly 202 work on the principle of abrasion grinding. Dry grinding uses particles to pass between grinding stones to reduce the size, while wet grinding involves dispersing the food ingredients in a liquid and circulating the resulting slurry to break down the particles against solid grinding media to reduce their size. Both operations happen in a contained area which helps in constricting material escape without grinding.

The advantages of the food processor 100, 200 are now explained. The food processor 100, 200 disclosed herein, use a single drive assembly 104 based on the need of the user. The multipurpose food processing systems 100, 200 provide a single device capable of performing both the wet grinding operations and dry grinding operations with minimal time. Moreover, the compact design of the food processor 100, 200 ensures storage space required is also drastically reduced in comparison to conventional food processing systems. The food processor 100, 200 eliminates the need for consumers to buy two different products for completely different applications by offering a single-product solution for both the dry grinding operation and the wet grinding operation.

The conventional grinders do not have an in-built speed control mechanism as the operating speed required for the dry grinding operation and the wet grinding operation is different. In the food processor 100, 200 disclosed herein, the same electric motor 306 is used for both the dry grinding operation and the wet grinding operation. That is a single drive unit can perform both the wet grinding operation and the dry grinding operation by just replacing the grinding assemblies 102 and 202 respectively. The speed control is achieved by the gear and helps in regulating the load as wet grinding will need a higher load requirement compared to dry grinding.

Advantageously, the gear assembly 120 is manufactured using the powder metallurgy process. The use of the powder metallurgy process for critical assembly structures provides metallic components of high quality at a lower cost without compromising the mechanical properties. Thus, a small household could afford to use this product in their day-to-day lives. Conventional machining operations work by material removal or molding processes to achieve the desired shape or part. The existing manufacturing process involves enormous wastage of materials increasing product costs whereas the use of the powder metallurgy process reduces the cost of the product.

Advantageously, for the wet grinding operation, the food processor 100 is provided with the wet cover unit 118 for enclosing the grinding unit 108. The wet cover unit 118 prevents the consumer from accidentally touching internal rotating components of the food processor 100. This feature increases the safety of the product and reduces the risk of accidental injuries to the consumer. Moreover, the at least one lid 118c is adapted to securely seal the aperture 118b when the first grinding assembly 102 is not in use thereby preventing contamination of the food processor 100.

Further, the replacement of the stationary grinding stone 216a and the rotary grinding stone 216c with oil extraction stones ensures oil extraction from food grains in regular households. In an embodiment, coconut oil, peanut oil, almond oil, and similar food items that require the same process may be extracted in regular households without any dependency on high powered mills. This eliminates the need for users to find high-power mills near their locality for the extraction of oil. Moreover, only smaller quantities of food ingredients or food grains may be used thereby improving efficiency of oil extraction and reducing oil wastage.

Additionally, in the food processor 100, 200 disclosed herein, the selection of the grinding assembly 102, 202 allows the consumer to achieve the desired texture and consistency of the final ground paste or ground powder. Further, the design of the grinding assemblies 102, 202ensures switching between the grinding assemblies 102 and 202 is quick and efficient, reducing setup times and increasing overall efficiency in the kitchen. The design of the grinding assemblies 102 and 202 also allow for better storage and space utilization in kitchens compared to using multiple specialized appliances. By offering versatility, efficiency, and adaptability to diverse culinary processes, the multipurpose food processing systems 100, 200 disclosed herein seeks to optimize kitchen resources and enhance culinary capabilities.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one ordinary skilled in the art to which this invention belongs. The system, methods, and examples provided herein are illustrative only and not intended to be limiting.

While specific language has been used to describe the present subject matter, any limitations arising on account thereto, are not intended. As would be apparent to a person in the art, various working modifications may be made to the method to implement the inventive concept as taught herein. The drawings and the forgoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment.
